Abstract
The design and construction of a Geiger-Müller counter spectrometer circle suitable for a wide variety of applications and of mechanical accuracy comparable with that of a precision power camera is described herein. Ancillary equipment for the study of integrated intensities from flat powder specimens has been constructed, utilizing monitored monochromatic radiation and making provision for automatic operation. Discussion of Geiger-Müller counter performance necessary to achieve a standard deviation of intensity measurements of about 0.5% is included with some results demonstrating the attainment of this accuracy.
